trying to find a way to make versabond thinset stay useable longer.
setting 12x12 tiles on wall.first timer doing actually fairly well.mixing up half a bag at a time working alone backbuttering every tile.

question

if i cover pail with airtight cover and transfer enough thinset to smaller bucket for at least four tiles at time that should keep thinset fresher longer correct

thank you for any input kurt out of work local#1 plumber

Thinset, a cement product, starts its chemical reaction as soon as it hits the water...once started, you can't stop it. As already noted, cold slows the reaction, but does not stop it - the chemical reaction makes its own heat.
